The attribute node is not supprted as of 2.0.112. As a workaround/alternative it was suggested on the Discord that I should be able to use RPR Lookup set to Vertex Color to get similar effect for use in shaders.

This doesn't seem to work.

I have attached screenshots from and example where I have exported an object from Houdini using alembic with vertex colors. In Blender I have renamed the attribute from "Cd" to "Col" to be Blender standard. EEVEE and Cycles can use this using the Attribute node. 

Vertex colors in RPR:

Preferred solution would be using the Attribute node as the other renderers. Using RPR lookup would be an ok workaround for this particular application.

Hmm, this works on our test scenes, can you attach yours?

I have made a similar example with vertex colors from H via .abc . This also works in cycles and eevee but renders black in RPR. In this case I have tried to make different names for the attibute. Both "Cd" or any other name works for the other renderers if the same name is given in the Attribute node.

So, looks like now it work correct, wait for future RPR official or beta release and then recheck from your side. Thank you
